A LATTICE DYNAMICAL INVESTIGATION FOR THE ZONE-CENTRE PHONON FREQUENCIES OF THE NaMnF3 PEROVSKITE
نویسندگان
چکیده
A short range force constant model has been applied to investigate the lattice dynamics of NaMnF3 in its orthorhombic phase. The calculated zone-eentre Raman frequencies agree fairly well with the measured values. The infra red measurements have been assigned the proper species for the first time on the basis of the present calculations.

Phonons in NaMnF3 perovskite using a rigid ion model
A rigid ion model has been applied to investigate the phonons in NaMnF3 perovskite in its orthorhombic phase. The calculated zone-centre Raman frequencies agree quite satisfactorily with the experimental values. The infra-red measurements have been assigned to proper species on the basis of the present calculations.
متن کاملAb initio investigation on the elastic, dynamical and thermodynamic properties of LiCl
The present work reports a study of the structural, elastic, dynamical and thermodynamic properties of rock salt (RS) LiCl within density functional theory. It is found that the lattice constant and elastic constants are in very good agreement with the other calculations or experimental values. The phonon dispersion curve along several high symmetry lines at the Brillouin zone (BZ) is determine...
متن کاملPHONON PROPERTIES OF A MULTIFERROIC BiFeO3 IN CUBIC PHASE
Multiferroic (MF) materials exhibit a highly coupled, spontaneous ferroelectric polarization and magnetization. Coupling between electrical and magnetic properties in multiferroic materials makes them a promising material for the design of multifunctional device applications, but also because of the interesting physics found in this class of materials. The role or absence of phonon softening in...
متن کاملA B INITIO CALCULATION OF THE KC1 PHONON FREQUENCIES
We have calculated the phonon frequencies of KC1 along symmetry directions using an approach which is a combination of the frozen phonon and force constants methods. We also calculated Griineisen parameters for all modes at X and L points in the Brillouin zone. Finally, the slope of acoustic dispersion curves around zone center were used to calculate the three independent elastic coefficien...
متن کاملبررسی ابتدا به ساکن خواص مکانیکی و گرمایی نانولوله‌های GaN با استفاده از محاسبات فونونی
In this work, we calculated the phonon dispersion of GaNNTs (4,0) and (4,4) by quantum ESPRESSO package using Density Functional Theory (DFT), pseudo potentials, and plane wave self-consistent field (PWscf) method. For the purpose of lattice-dynamical calculation and phononic properties, we used PWscf and Phonon codes. The former produces the self-consistent electronic and all related computati...
